BiXPower BX3699 – 504Wh High-Capacity
Rechargeable Backup Battery for Philips
Respironics DreamStation CPAP &
BiPAP Machines
Enjoy dependable backup power with
the BiXPower BX3699-KF562VX-12V-S10,
a high-capacity 504 watt-hour
rechargeable battery system designed
for compatible Philips Respironics
DreamStation CPAP and BiPAP machines
requiring 12V DC power.
This complete power package combines
a powerful BX3699 rechargeable battery
with a compact slide-on DC-to-DC
converter that delivers regulated
12V DC output.
With its large battery capacity,
convenient carrying handle, and
integrated converter design, this
system is ideal for emergency backup
power, camping, off-grid use, and
locations where AC power is unavailable.
Under favorable low-power conditions,
the battery may support several nights
of CPAP operation without heated
humidification. Actual runtime
depends on machine power consumption
and operating settings.
504Wh High Capacity
Large rechargeable energy reserve
for extended CPAP operation.
Regulated 12V DC Output
Provides constant 12V power through
the included converter.
Slide-On Converter
Attaches directly to the battery
output socket for convenient use.
Approximately 5.1 lb
Portable battery with integrated
carrying handle.
AC Charger Included
Recharge from compatible
110–240V AC outlets.
Built-In Protection
Electronic protection against
common battery electrical faults.
Complete 504Wh DreamStation
Battery Power System
BX3699 battery with slide-on
12V power converter installed.
Unlike battery systems that require
a separate converter connected by
multiple cables, the BiXPower
KF562VX converter slides directly
onto the BX3699 battery output
socket.
The integrated arrangement helps
keep the power system compact
and reduces unnecessary cable
connections.
The battery supplies power to
the converter, which regulates
the voltage to 12V DC for
compatible DreamStation machines.

DreamStation 2 or other CPAP brands.
504Wh High-Capacity
Rechargeable Battery
The BX3699 battery stores 504Wh
of nominal energy, providing a
large rechargeable power reserve
for compatible medical devices
and other supported DC applications.
The battery uses a rechargeable
lithium-ion cell configuration
with built-in electronic protection
and a durable ABS plastic enclosure.
Compact Size and Carrying Handle
Compact BX3699 battery with
integrated carrying handle.
The battery weighs approximately
5.1 pounds (2.33 kg) and measures
about 9.8 × 4.4 × 3 inches.
Its integrated carrying handle
makes the battery convenient to
move between rooms or transport
for camping and other off-grid
applications.
Easy-to-Use Battery Controls
Battery controls and connection points.
The BX3699 includes several
convenient operating features:
-
Four-Level LED Indicator:
Displays approximate remaining
battery capacity.
-
On/Off Switch:
Controls battery output power.
-
Charging Port:
Connects to the included
AC battery charger.
-
Power Output Socket:

DC power converter.
Battery Status Indicator
Battery power status indicator.
The LED power indicator provides
a convenient way to check the
approximate battery charge level
before use.
Slide-On Regulated 12V
DC Power Converter
Compact slide-on 12V DC converter.
The included KF562VX power converter
attaches directly to the battery's
output socket and converts the
battery's variable voltage to
regulated 12V DC power.
This is important because the
BX3699 battery operates at a
higher internal voltage that
changes during discharge.
The converter maintains the
12V output required by compatible
DreamStation machines.
Converter Benefits
- Constant regulated 12V DC output
- Maximum output current: 5A
- Maximum rated output power: 60W
- Slide-on battery connection
- Compact and lightweight design
- Dedicated CPAP output cable
Important:
The converter's rated maximum
output is 12V at 5A, or 60W.
Confirm that your CPAP machine,
including any heated humidifier
or heated tubing, does not exceed
this power rating.

How Long Can the BX3699
Power a CPAP Machine?
The BX3699 provides 504 watt-hours
of nominal battery capacity.
Actual runtime depends on the
machine's average power consumption,
pressure settings, heated humidifier,
heated tubing, battery condition,
and conversion losses.
The following examples assume
90% usable energy after conversion
and other losses. This is an
illustrative assumption, not a
verified efficiency specification.
| Average CPAP Power |
Estimated Runtime |
| 10W | 45.4 hours |
| 12W | 37.8 hours |
| 15W | 30.2 hours |

| 25W | 18.1 hours |
| 30W | 15.1 hours |
| 40W | 11.3 hours |
| 50W | 9.1 hours |
These figures are calculated
estimates, not guaranteed runtimes.
Actual performance can vary
substantially depending on
equipment and conditions.
Tips for Longer Battery Runtime
